Yes, leaving children unattended in a vehicle is illegal in many states, though specific age limits and time restrictions vary significantly[1]. California prohibits leaving children under 6 alone without supervision from someone at least 12 years old when conditions pose a risk[2]. Florida makes it illegal to leave children under 6 in a car for more than 15 minutes[3]. Texas restricts leaving children under 7 unattended for more than 5 minutes[4]. Even in states without specific statutes, child endangerment laws typically apply when leaving a child in a vehicle creates risk of harm[1].
Why This Law Exists: The Deadly Risk
The statistics behind these laws are sobering. Since 1998, 1,041 children have died from pediatric vehicular heatstroke in the United States[5]. An average of 37 children die each year after being left in hot vehicles, with 39 deaths recorded in 2024 and 31 already in 2025[5].
Vehicle interiors heat rapidly—even on mild days. A car parked in 70°F weather can reach 104°F within 30 minutes[6]. On a 90°F day, interior temperatures can exceed 130°F within the same timeframe. Children’s bodies heat 3-5 times faster than adults, making even brief exposure dangerous.
The circumstances of these deaths reveal important patterns[5]:
- 52.6% of children were forgotten by caregivers
- 23.8% gained access to vehicles on their own
- 21.8% were knowingly left by caregivers
Over half of victims (54%) were under 2 years old[5]. These statistics underscore why lawmakers treat leaving children in vehicles as a serious offense regardless of intent.
State Laws Overview
Laws vary considerably by state. Some specify exact ages and time limits; others rely on broader child endangerment statutes[1].
| State | Age Restriction | Time Limit | Key Provisions |
|---|---|---|---|
| California | Under 6 | Any duration if risk exists | Requires supervisor age 12+ if leaving child[2] |
| Florida | Under 6 | 15 minutes | Stricter if engine running or immediate danger[3] |
| Texas | Under 7 | 5 minutes | Requires companion age 14+ if leaving child[4] |
| Indiana | Under 6 | 30 minutes | Class A misdemeanor[7] |
| Michigan | No specific age | Risk-based | Illegal if circumstances pose unreasonable risk[8] |
| Illinois | Under 6 | 10 minutes | Must not endanger health/safety |
States With Specific Age-Based Laws
Approximately 20 states have passed legislation specifically addressing children left unattended in vehicles[1]. These laws typically set:
- A minimum age below which children cannot be left alone
- Maximum time limits for leaving children unattended
- Requirements for supervision by older children or adults
- Enhanced penalties when the vehicle is running or keys are accessible
States Without Specific Laws
States without dedicated unattended child laws still prosecute cases under general child endangerment, neglect, or abuse statutes[2]. In New Jersey, courts have held that leaving a child alone for even 5-10 minutes can constitute abuse or neglect[9]. The absence of a specific statute does not mean the action is legal—it simply means prosecutors use different legal frameworks.
Penalties and Consequences
Criminal Penalties
Consequences range from misdemeanor citations to felony charges depending on circumstances and outcomes[8].
Texas: Class C misdemeanor, fines up to $500[4]
Indiana: Class A misdemeanor, up to $5,000 in fines and one year imprisonment[7]
Michigan penalties escalate based on harm:
- No physical harm: Misdemeanor, up to 93 days jail and/or $500 fine[8]
- Physical harm: Misdemeanor, up to 1 year jail and/or $1,000 fine[8]
- Serious physical harm: Felony, up to 10 years prison and/or $5,000 fine[8]
- Death: Felony, up to 15 years prison and/or $10,000 fine[8]
Child Protective Services Involvement
Beyond criminal charges, leaving children unattended in vehicles typically triggers Child Protective Services investigations[2]. Even first-time incidents may result in:
- Mandatory parenting classes
- Home visits and ongoing monitoring
- Temporary custody arrangements in severe cases
- Permanent records affecting future custody determinations
Civil Liability
If another child or bystander is injured while attempting to rescue your child from a hot car, you may face civil lawsuits[2]. Many states have “Good Samaritan” laws protecting rescuers who break windows to save children, but the vehicle owner may bear liability for damages.
Understanding legal consequences in vehicle-related situations helps with broader automotive decisions. For related coverage, see our guide on what happens when your car is totaled.
Factors That Affect Legal Consequences
Courts and prosecutors consider multiple factors when determining charges and penalties[2]:
Environmental Conditions
- Outside temperature (both hot and cold extremes)
- Whether windows were open or cracked
- Whether the engine/AC was running
- Direct sunlight exposure
Duration and Circumstances
- How long the child was left unattended
- Whether the parent could see the vehicle
- Distance from the parent to the vehicle
- Whether the vehicle was locked
Child’s Age and Condition
- Age and developmental stage
- Any medical conditions or special needs
- Whether multiple children were involved
- Actual harm or distress experienced
Intent and Pattern
- First-time incident vs. repeated behavior
- Whether leaving the child was intentional or accidental
- Parent’s responsiveness when alerted
A parent who runs into a gas station for 2 minutes on a 65°F day faces very different consequences than one who leaves a toddler for 30 minutes during summer heat[2].
Safe Practices to Follow
Never Leave Children Unattended
The safest approach is never leaving children alone in vehicles, regardless of duration or weather[5]. What seems like “just a minute” can extend unexpectedly due to lines, distractions, or emergencies.
Prevention Strategies
- Place essential items in the back seat – Put your phone, wallet, or bag near your child’s car seat so you must check the back before exiting
- Keep vehicles locked – Prevent children from accessing parked cars on their own (23.8% of deaths involve children gaining access independently)[5]
- Establish check-in routines – Create protocols with daycare or school for notification if your child doesn’t arrive
- Use reminder technology – Several vehicles and aftermarket systems now include rear-seat alerts

What to Do If You See a Child in a Hot Car
If you encounter an unattended child in a vehicle showing signs of distress[5]:
- Call 911 immediately
- If the child is unresponsive or in clear danger, many states permit breaking the window to rescue them
- Stay with the child until emergency services arrive
- Attempt to locate the caregiver
Most states now have “Good Samaritan” laws protecting rescuers who break into vehicles to save children[1].
Key Takeaways

- Even states without specific laws prosecute cases under child endangerment statutes—the absence of a dedicated law does not mean the action is legal
- Since 1998, 1,041 children have died from vehicular heatstroke in the US, with over half being under 2 years old
- Penalties range from fines under $500 to felony charges with up to 15 years imprisonment when serious harm or death results
- The safest practice is never leaving children unattended in vehicles regardless of duration, weather, or whether the AC is running
Frequently Asked Questions
Can I leave my child in the car if the engine is running with AC on?
Even with air conditioning running, leaving children unattended is illegal in most states and dangerous[3]. AC systems can fail, vehicles can be stolen with children inside, and children may accidentally shift gears or injure themselves with vehicle controls. Many state laws specifically address this scenario with enhanced penalties[3].
What age can a child legally stay alone in a car?
This varies significantly by state. California and Florida set the threshold at 6 years[2][3]. Texas sets it at 7 years[4]. Some states like Michigan have no specific age—legality depends on whether circumstances pose unreasonable risk[8]. Even where older children may legally remain in vehicles, weather conditions and duration still matter.
Can I be arrested for leaving my child in the car for just a few minutes?
Yes. Several documented cases involve arrests for leaving children unattended for 5-10 minutes[9]. Law enforcement and prosecutors evaluate the totality of circumstances including temperature, the child’s age, and perceived risk. Even brief durations can result in charges if conditions are deemed dangerous or if the child shows distress.
What if I’m parked right outside and can see my car?
Proximity and visibility are factors courts consider, but they don’t necessarily make the action legal[2]. State laws that specify time limits (5 minutes in Texas, 15 minutes in Florida) apply regardless of whether you can see the vehicle. The key question remains whether the circumstances pose a risk to the child’s safety.
